You don’t have to go to the tropics to have a backyard banana grove. In northern temperate climates, between USDA Plant Hardiness Zones 5 and 7, there are several varieties of decorative banana trees. It’s understandable that people in these areas might be concerned about how to winterize banana plants if they plan to grow them outside. Winterizing banana trees is something we’ve looked into in depth in order to provide you with the most accurate information possible.
Just before the first frost, prepare your decorative banana tree for the winter by covering the roots with a blanket of snow.
Step by step instructions are below:
- Only one foot of pseudostem should remain above ground after removing all dead foliage.
- Mulch the top of the pseudostem with a thick layer of mulch to protect the root system.
With just two simple procedures, you can ensure new spring development for ornamental banana plants in the winter. There are three ways you may protect the plant’s root system from harsh winter weather, and we’ll go over each one in detail in the following section.
How Cold of an Environment Can Banana Trees Tolerate?
If you live in the USDA Plant Hardiness Zone 5, you can plant ornamental banana trees even if the temperature drops to -20°F in the winter.
How to Prepare a Banana Tree for Winter?
Protecting banana trees from harsh winter temperatures is possible if you can’t relocate them indoors for the season. Winterizing the banana tree before its first frost is essential in order to avoid any damage to its root system.
1. Cut Away Any Dead Foliage
After producing blossoms, banana plants naturally die (or fruit on fruit-bearing varieties). Cold temperatures will also cause the foliage to wither. Remove the plant’s dead foliage near the conclusion of its life cycle, in late fall.
Remove wilted and browning leaves from the plant. Leaves that have fallen to the ground can be left in place since they will serve as insulation. A 1-foot section of pseudostem should be left standing above the ground after cutting the pseudostem at an angle.
2. Insulate the Root System
When it’s cold outside, the rhizome of a banana tree goes into hibernation, just like a bulb would in a cold climate. The rhizome regenerates new roots when the soil warms in the spring, and a new plant grows.
Add a thick layer of insulation to the earth above the underground rhizome of an ornamental banana tree to protect it from the harsh winter temperatures. The remaining pseudostem should be completely covered with mulch, wood chips, or leaves.
Put a sheet of plastic over the entire mulch pile as an extra layer of defense. Using hefty logs, bricks, or stakes, secure the edges of the plastic. The pile should not be uncovered or removed until spring, when there is no longer a risk of frost.
For decorative banana plants, an insulated cage is an alternative to stacking mulch. Install a fine-mesh wire fence with a small weight around the remaining pseudostem’s perimeter to keep animals out.
Fill the inside of your fencing with either mulch, leaves or straw. Instead of a haphazard jumble, the cage will keep the insulating material neat and contained. Place a plastic sheet on top of the cage and secure it in place.
First, remove the dead leaves from an ornamental banana tree before wrapping it with insulation. Avoid water gathering in the stem by cutting each leaf at an angle. Let go of the remaining pseudostems.
The next step is to cover the pseudostem completely with either fleece or burlap, according on your preference (or hessian). If you need help moving the huge piece of fabric around the stem, consider enlisting the aid of a friend or family member. Use string to keep the wrap in place. For banana trees that produce fruit, this strategy is often advised.
Caged insulation can be used to protect the wrapped banana tree during extremely harsh winters.
Do Banana Trees Come Back After a Freeze?
When temperatures drop below freezing, the decorative banana tree’s foliage (leaves, blossoms, and pseudostems) dies. Wilting and browning of the leaves are inevitable. The stem will turn brown and mushy over time. The plant’s rhizome is dormant, despite the fact that the foliage is buried beneath the soil.
An insulated rhizome can withstand a cold snap. Dormant rhizomes will sprout new leaves and stems in the spring when the weather warms. The rhizome of a newly planted decorative banana tree can be protected for several summer seasons if it is prepared before the first frost.
For each summer, your landscape will be filled with magnificent, fully developed foliage that towers between six feet and twelve feet tall from ornamental banana trees.
Which is the Most Cold Hardy Type of Banana Tree?
In USDA Plant Hardiness Zones 5 through 10, Masa Basjoo grows well. In the summer, Musa Basjoo loves full sun, just like most banana trees. The height of this little banana tree is between 8 and 10 feet. During the winter, Musa Basjoo will grow back if it is protected from the elements.
Should I Cut Down My Banana Tree?
To prepare for the next winter, you can trim back your decorative banana tree. However, this strategy is normally not suggested for fruit-producing trees. The spring growth of ornamental trees will be boosted if the dead foliage is removed.
In order to avoid water from accumulating inside the pseudostem, cut it at an angle Keep a pseudostem of about a foot above ground level. Your preferred method of insulating the remaining stem above ground should be used, as we previously described.
Your property will always have a tropical feel to it if you winterize your ornamental banana trees.

Banana Plants in Winter
A banana’s leaves will die if the temperature drops below freezing, and even a few degrees below may destroy the entire plant. It’s possible that your tree’s roots will be able to produce a new trunk this spring if your winters never go below the upper 20s Fahrenheit (-6 to -1 C). However, if it gets any colder, you’ll have to bring it inside.
Treating banana plants as annuals is the simplest method to care for them over the winter. Planting a new tree in the spring and having it dominate your garden for the duration of the summer is possible due to their rapid growth in a single season. Allow it to die in the fall and begin the cycle all over again the following year.
Banana trees need to be brought indoors if you intend to keep them over the winter.
For containers, red banana plants are preferred since they are smaller. Keep a red banana in a bright window and water it frequently if you have one that’s a manageable size before the fall temperatures begin to decrease. Even if the plant is given the best possible care, it is likely to die. However, it should last till April.
Overwintering a Banana Tree Outside
Banana plants that are too large to fit inside your house will not overwinter successfully. The plant should be pruned back to 6 inches (15 cm.) above the ground and either mulched or stored in containers in a cool, dark spot for the winter, watering it very sparingly. Overwintering foliage on hardier plants is another option.
In the spring, give it a vigorous watering to encourage new growth. As long as the plant survives the winter without its stem, it’ll be able to thrive for another year. There is a good chance that hardy banana varieties may return, but they may need to be pruned of any dead growth that was left on.
Winterizing using the Chicken Wire Method
Your banana tree should be chopped down to 2-3 feet after the first good frost, when the leaves begin to turn brown (60-90 cm). Compost the leaves when you’re done with them. Leave the banana stump in the center of the square and stake four stakes about three feet apart. Chicken wire or fencing wire should be wrapped around the poles to form a 3ft x 3ft square. To keep water out, place a tiny plastic bag over the banana’s stump. 3 to 4 feet is the ideal height for the chicken wire Until the basket is full, start filling it with leaves. Despite the frigid winter temperatures, the banana tree is able to thrive on those warm, bright winter days.
Winterizing using the Water Pipe Insulation Method
Water pipe insulation, available at most hardware stores, can be used to cover even the largest banana trunks. Make sure that the top is folded over so that no water gets inside the insulation. After harvesting the leaves of a banana plant in the fall, arrange them on top of each banana trunk. Other organic materials, such as grasses or twigs, can be substituted for the walnut leaves. Mulch to the deepest depth. Remove the mulch and plastic in the spring and watch it grow back swiftly.
What You Need to Know About Bananas
In the United States, bananas are one of the most common fruits eaten by people of all ages. A banana has a wide range of nutrients. Vitamins B6 and C, potassium, fiber, and many other nutrients can be found in this food. There are numerous health benefits of bananas that include lowering blood pressure to avoid asthma and cancer.
Berries, as it turns out. What’s going on? A berry is a flower with a single ovary that generates a large number of seeds. Strawberry and raspberry berries are not included in this category.
Do’s You Need to Remember to Keep your Banana Trees Happy During Winter
If you have a garden, bananas can be grown there, too. It takes a lot of patience and effort to grow bananas. In the course of nine months, banana plants fully mature and produce fruit.
Banana plants, as we all know, thrive in warm, humid climates. If the temperature falls below about 55°F, banana leaves stop growing. Furthermore, at 32°F, the leaf is destroyed, and at 22°F and lower, the underground rhizomes perish.
Other banana cultivars, on the other hand, may thrive in temperatures as low as 0°F. Even if the leaves are harmed by the freezing temperatures, the roots will continue to grow and thrive. Bananas from these cold-hardy plants aren’t edible, which is a shame.
However, banana trees are excellent houseplants, and may be grown indoors. Bananas, even those that are robust to cold, need to be shielded from the elements. In order to thrive and safeguard your plant over the winter if you’re planting little banana plants, follow these guidelines.
DO: Take them indoors
Put your banana plant in a container and bring it indoors if it’s small enough. It is better for bananas to grow on soil that is constantly moist. Spray a little water on the leaves to keep them moist.
Place it in a location where the plants can still get some sunshine. In addition to offering protection, a potted plant is a lovely addition to any home.
DO: Give them plenty of wrapping
To protect the plant from the cold, you can wrap it in a blanket or something similar. Before wrapping, be sure to remove any dead or diseased leaves. After that, take a 6 meter-long saw to the plant.
Leaves, straw, and other mulching materials can be used to cover the rest. The rhizome is kept at the pseudostem by wrapping the corm. When the weather warms up, you can remove the plant’s protective covering and let it to flourish.
Heavy snowfall can be found in several regions. In certain places, you can dig up the root and store it in a jar in your basement or a covered area to preserve it from freezing. The plant will then go into hibernation as a result of this method.
Make sure the soil isn’t drying out by applying a small amount of water to the plant. Cut the plant to around 4 inches in height and begin replanting it as soon as the weather improves.
Why Give Greenhouse Gardening a Try?
It’s time for the cold weather to arrive! Keeping our plants healthy and happy can be a challenge.
Farmers used to be unable to raise crops in the winter. However, because to advances in technology, even in the coldest months of the year, planting may take place. If you have a hobby greenhouse, you can cultivate plants that thrive in warm, humid conditions all year round.
With a hobby greenhouse, you’re able to provide plants with a place to call home, one that’s tailored to their specific requirements. In addition, it protects your plants from pests and animals that could inflict significant harm on your efforts in the garden. As a last point, a hobby greenhouse can provide protection from inclement weather, such as heavy rains, high winds and hail, as well as snow.
Final Thoughts on How to Prepare Banana Trees for Winter
Bananas, like all plants, require extra attention throughout the winter months if they are to survive. If you’ve learned how to winterize banana trees, you might want to try growing them in your own hobby greenhouse to see what all the fuss is about.
